CA R-AXLE BOX.

SPECIFICATION'formingpart of Letters Patent No. 269,995, dated January 2, 1883.

' Application filed March 30, 1882. (No model.)

To all whom it may concern Be it knownthat l, JAoKsoN R. BAKER, of Jersey City, Hudson county, State of New Jersey, have invented anew and useful Improveinent in Oar-Axle-Boxes; and I do hereby dea full, clear, and

exact description of the same, reference being ure 1 represents a side view had to the accompanying sheet of drawings, making part of this specification.

This invention is in the nature of an improvement in car'axle boxes; and the invention consists in a car-axle box with its lid hinge provided with a pivotal bolt keyed in position in the hinge by soft metal or alloy, as is more particularly described hereinafter.

In the accompanying sheet of drawings, Figof my invention; Fig. 2, a front view of same; Fig. 3, a longitudinal section of same, taken in the line a: a Fig. 1.

This invention pertains particularly to the hinge of an axle-box which unites the boxproper to its lid.

1n the hinges ordinarily made the pivot of the hinge, being secured sometimes by a screwnut and at others by a key orpin passed transversvlythrough its projecting ends, will frequently work loose and out of place, the door of the box falling off and exposing the axle- 3 3 journal to the dust, speedily cutting the brasses,

and resulting in what are known as hot boxes. To obviate this difficulty I construct my hinge with lugs A and b and c, and bore out the interior of the lug A of the hinge with a cyllndrical Opening, a, somewhat larger in diameter than is the pivot-bolt B, which is to pass through it, the lugs b and c of the hinge,

however, being bored with holes at and e,ot'

such size as will snugly receive the pivot-bolt B when inserted in them. This .pivot bolt or pin B is ot'suitablelength to pass through the lugs 11 and c and the lug A, and it has turned in it midway between its ends a groove or recessrU, entirely encircling it. Through the top of the lug A and into the cylindrical opening a is also bored '2. hole, f. Now, when the lug A on the box is fitted between the lugs b and c on the lid of the box the pivot bolt or pin B is inserted through the holes (2 and c in the lugs 12' and c, and through the cylindrical same within the lug A and preventungit l'ro'in working out of its position in the hinge, confining the pin Bin place as long as it may be desired. In case it becomes necessary to remove the lid of the box, as when the lid becomes broken or for any other reas0n,it is easily and quickly accomplished by drifting the pivot-pin B through the lugs A, b, and c, the soft-metal alloy surrounding the pin in the lug A readily yielding for that purpose.

I am aware that it is not new to divide caraxles and connect theirends by boxes in which a soft-metal bcariu g has been provided for the same, such soft metal remotely serving to hold the ends together or in the box; but I am notaware thatacar-axle box has had its lid hinged toit in the manner and by.the means I have herein shown and described.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

' l. A car-axle box having its lid secured thereto by a recessed pin arranged in lugs on the box-and lid,and retained in position therein by soft metal embracing its recessed portion, substantially as shown and described.

2. In a car-axle box, the lug A, having a. cylindrical opening, a, therein, and the pin-re ceiving lugs 11 0, combined with a recessed counecting-pin, B,- and an alloy engaging said-recessed pin within the opening a in the lug to hold the pin in and described.

3. The lid of an axle-box, provided with a hollow lug, A, a pin, B, having a recess or groove, 0, and an alloy surrounding such pin within the lug to hold it therein, combined with bearings for such pin on the box to secure the lid thereto, substantially as shown and described.
